Stagecoach is an expansion board that harness the power of up to seven Overo COMs networked on a single board. This is for engineers and companies looking at creating tiny supercomputers. The Stagecoach brings out 7 USB OTG ports and 1 serial-over-USB console port in addition to Ethernet connectivity.
Once you have tested the board, you may use Geppetto online to design and customize a board like Stagecoach for your own project.
A cluster computer board for up to 7 Overo COMs networked via 100Mbps switched Fast Ethernet communications. Also features 7 USB OTG ports and USB console. The fully populated board draws less than 20W. Power supply included.
You may also want to include Janus to have USB console port access to the Overo COM.
